Answer:
y = 22/x
Step-by-step explanation:
We have given that y varies inversely with x.
y ∝ 1/x
y = k/x where k is constant of proportionality.
We have given that x = 2 when y = 11.We have to find the value of k.
Putting values in given equation, we have
11 = k / 2
k = 11 × 2
k = 22
Putting the value of k in given equation, we have
y = 22/x which is the answer.
y =
given that y varies inversely with x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition x = 2 when y = 11
k = yx = 11 × 2 = 22
y = ← equation of variation
The ladder will go 6 feet up.
